A great idea... BUT WHY spend 2 out of the 4 years staring at bloody red sand/dirt? lol
Did a lap in the mid 80s in a full length bus decked out with everything we needed. Took us two and a half years and certainly didn't see it all. Enjoy the trip. You won't want to come home.
Enjoy mate, sing out when your headed to our neck of the woods....let you buy me a xxxx.....LOL
